In the embodiment illustrated, see Figs. .land 2, there are shown twohousing sections 1 and 1a, which are connected to one another in anysuitable manner so that a positive and accurate registration of the .twosections is attained, and therewith positive and accurate registrationof the mechanisms contained by the respective sections. In the presentinstance, the hinges 1d are provided along the opposing edges or' thesections 1 and 1J on one side, by which the sections are pivoted to oneanother, and the pin and socket arrangement 1g provi-ded along theopposing edges ozt the sections 1 and 1?* on the other side, by whichthe sections are positively and accurately anchored to one another in apredetermined registered positionrelative to one` another. l

. At the opposite sides of the section` 1, ad-v jacent to its front end,are provided the bracket-s 3 and 4, at the upper ends of which brackets3 and 4, is secured the rail 5 Fig. 4 bevelled at the upper and lowerends .of its rear face; and a short distance removed from thelower endsor the brackets 3 and 4, at 7 and 8, there is journallcd the cylindricalbar 6 provided at its intermediate portion with the elongated teeth 6and at its end adjacent to bracket 3 with the teeth 6b.

0n the rail 5 there is reciprocably mounted the film carrier to overhaninto housing section 1a and reciprocatedg transversely thereof.

The carrier 50 comprises essentially a sheet metal traine or bodyportion 51 travelling along vthe front 'face of the rail 5 with anelongated opening 50a 'formed therein above and parallel to the :rail 5to accommodate the passage oli' light, there to be interes ted by a.portion of a film. Only a portion o` the opening 502l will be exposed atany one time in the present instance, `for the passage of light rays.The body portion lterminates at its upper end in forwardly bent, upwardlextending arms 94, 94, and at the upper en s thereof, there are mountedthe journal pins g5, 96 yfor receiving the iilm spool F in The bodyportion v51 is held in place on the rail 5 by means of the bevelled.face block 53, Fig. 3 disposed on either side of the opening 50a andengaging 'the rear edge of the rail 5, the block 54 secured to the body`portion 5l below Athe rail 5 engaging Ythe lowerk rear edge of the railThebody portion extends downwardly below the rail 5 forming thelaterally extending arms" 51 and 51", terminating in the forwardlyextending portions 103, 104, to which are secured the forwardlyextending bracket portions 111 and 120 ci the apron 90. ally extendingarm 121 to which is pivotally connected a depending ylinger 122 having aforwardly extending lip 123 provided with a bearing pin 10.8. 'On 111there is pivotally mounted the disk 107 having a locking pin 109 betweenwhiehand the pin 108 the lower receiving film spool is mountechthe diskbeing accurate to rotate the lower filml spool in the usual way. y

The body portion 51 extends below the arms 51a and 51b in the form ofthe bracket 124, Figs. 3 and 4 terminating inthe laterally extending arm125 having 'forwardly extending finger portions 126, 126, between 'whichis journalled the roller 106.

The apron 90 depends a considerable dis-v tance to form an extendedguiding surface for maintaining t-he hlm straight and practically inContact with the bracket 124, while passing to the roller 10,6. A

The portions 94, 94, as shown in Figs. 3 and 4, support the rollers 98,93, adjacent 'to the body portion 51, one roller above .the opening 50'and the other below the opening 50a.

In the course ofoperation the new film spool will be secured to thebrackets 94, 94, at the upper end of the bod portion 51, and the filmthereupon passed t own between the rollers 98, 98 and the body portion51, across the opening 50, and then down between the apron 90 and thearms 511l and 51, then down below the roller 106 and up to the receivingspool mounted between the vdisk 107 and the bracket 122.

As shown in' Figs. 1 and 2, the opening 50 is in line' with the opening127 in the housing section l* so that when projecting, the pictureregistering with the opening 127 maybe projected through saidopeningupon the screen, or in turn `when taking pictures,

disposed in the opening 50a registermg with the opening 127 may beexposed for taking a picture. l Y I The resent invention contemplatesmeans lfor taking a series of pictures successively in a rowtransversely of the film, and to project such pictures inthe same order.To 'this end the elongated opening 50 is ,provided in the carrier 51,and the carrier will be recifproeated transversely, and successive partso the strip registering with said opening 50 will register with theopening 127 to receive a picture or to project one.

The mechanism for reciprocating the car rier will now be described. Onthe bar 6 there is slidably mounted the bracket 55 which lis recessed atits forward end to .receive thc vertically reciprocating slide 61, Figs.2 and 10, which hns a vertically extending slotV 66 The bracket portion120 has a laterl' meshing with the gear 18 affixed to the counter shaft15, to which is also fixed the bevelled gear 14 meshing with thebevellcd gear 15 connected by a stub shaft to one face of the clutch 28,Fig. 2. The other face of the clutch 28 is secured to the shaft 24mounted in the section 1a, the faces of the clutch 28' being adapted toengage when the housing sections 1 and 1a are swung into closedpositionfas shown in Figs. 1 and 2. The shutter, of usual construction,for cooperating with the lens opening of the lens 2O extending throughthe wall 1, is supported adjacent to the wall 1, and as shown in 2, isoperatively connected by means of the shafts 25 and 24 and intermediatebevel gears -to the clutch 28 so that the actuation of the handle 11will cause the shutter 30 to be rotated.

During the extended period of rest at the end of stroke of the sector 86before its return, two pictures will be taken, a picture during thefirst half of the period of rest, whereupon the film will be advanced adistance, to start a new row of pictures and thereafter during the lasthalf of` said extended period of'rest a, second picture will he taken,constituting the rst picture of the new row. This extended period ofrest and the advance of the film is timed so that the shutter will haveafforded two exposures, one during the first half' of the extendedperiod of rest and the other during the lastV half of the extendedperiod of rest. The longitudinal feeding of the film will now bedescribed.- The slide 61, as shown in Figs. 8, 8, 10 and 11, has atoothed portion .rocked to and fro by successively striking the pin 17bat one half of its turn and the pin 17G during the other half of itsturn about one hundred and eightyv degrees. The pin 17 is pivotallyconnected to the linlr 17f which is pivotally connected to the bracket 3and to the elliptical link 17 e through the enlarged opening of whichthe shaft 11 eX- tends. The pin 171 pivotally connects the other end ofthe link 17G tothe sector 118 pivotally connected. to the bracket 3 andin mesh with the teeth 6b..

Extending from the upper portion of the slide (il and substantially atright angles to the slot 66, there are provided the arm portions 64, seeFigs. 8, 10l and. 12. There are provided two lever arms 67'pivotallyconnected at their adjacent ends to the pin 62 'secured to the bodyportion 51 and extending through the elongated slot 66. The arms G7 havethe laterally' extending slots 68 to re ceive the pins 65 of the arms64, and have laterally extending slots 7G p to receive the studs 69secured to they depending portions 74y of the rear gripping member-68.The

vdepending portions 74 have forwardly eX- tending portions formingslide-ways engaging the. -slide tracks 75 integral with the main bodyportion 5l .and extending forwardly therefrom. The outer ends of thearms 67 are provided with pins 71 to form two abutments for the tensilespring 72 to connect the outer ends of the arms 67 to one another. Thegripping member 68 as shown in Fig. 8, is lprovided with a flange 86 tocooperate either with the block 54 or the eccentric cam 140 pivotallyconnected to the block 54 to limit the upward movement of the reargripping member 68.

As constituting the forward gripping member to cooperate 'with the reargripping member 68, there is provided the bar having enlargements 81 atboth ends, see Fig. 9, for engaging the film between such enlargementsand the faces 79 of the rear gripping member 68. The bar 8O is anchoredto 'the gripping member 88 by means of the pins extending through theends of the two gripping members. There are provided recesses around theopening in the members v76 and 80 facing one another to form seats forthe springs 82c surroundin the pins 78 and serving to open the grippingmembers. For closing the gripping members there are provided theY-shaped upwardly extended members 82 which are pivotally connected attheir lower ends to the pins 78, the pins 78 having heads 130 and 131 ontheir rear and forward ends respectively for maintain ing the partsirl-place. The bifurcations of the members 82 cooperate with the pins 84secured to the rail 5, as shown in Figs. 10 and 12.l The lower ends ofthe members 82 are provided with bosses which 'have-projections82n tosit into the V-shaped recesses 77 formed in the adjacent ends of thegripping member, 68 as shown in Fig. 1l. Just below the pins 78 themember 68 is provided with 'the depending portions 85 Fig. 10 whichcooperate with the abutments 102 of the body member 51 to limit thedownward movement of the gripping member 68.

The operation of these gripping members is as follows:

With the rotation of the handle 22, the sector 118 will be rocked to andfro in turn vertically to reciprocate the slide 6l. The mechanism 'is sotimed that the downward movement of the slide 61 will take placrl atboth ends of travel of the carrier, Fig. 12 showing the position of thegripping member 61 at one end of travel of the carrier.innne diatelyafter the gripping member 68 has been lowered. When the gripping memberis in the end-position of travel, the projections 82IL will have beenrocked out of the V-shaped recesses 77 in the member 68, into theposition shown in Fig. 13, and thereby Having procured an ordinarycommercial film, the loading being similar to that with an ordinary.still camera, the section 1, is opened and the film and paper' coveringis placed upon the upper spool carrier. The

pressure rollers 98 are thereupon raised, the carrier 50 placed in thecenter of the machine, with the gripping-members@ and 80 opened. Then,upon retracting theauxiliary locking jaws 87,1 the film and paper can 22is turned, the main driving mechanism` will function, turning theshutter 30 at the proper speed, driving the cam 32 to cause thefsector36 to oscillate and thereb recipe rocate the carrier 50 back and fortintermittently with absolute registration, making seven distinct stopseach way. At the end of the said travel of the carrier, the film islmoved down by the gripping members 68 and 80 and at the center of thetravel of the carrier, these gripping members are returned, the loweringand raising of the grip ping members being accomplished by the cam 17 ofthe main driving shaft 11 cooperating with the pins 17b and 17, respec-J tively, and oscillatin 1 to rock the shaft 6, thereby causing the sevethe lever or sector 1,18

eral parts of the feeding mechanism to function, the spring 72 ulcrumed,onthe levers 67, causing the gripping members 68v and 8'0 to snap downor lup, without 'loss oit/motion to ensure proper registration.

While the film carrier is movedtoward the center of the machine thegrippin jaws 68 an'dSO areA gradually opened b t e action of the arms 82swinging a out the pins 84, and remain opened untn une grip pingAmembersA have been raised, when the fjawswill' close as soon as theprojections -82L will have been actuated out of the V shaped recess 77.As the carrier approaches the end positions of travel, the .arms 92 ofthe auxiliary locking jaws 87 will be en-.

gagedby the cams 93 to disengage the locking jaws 87, in turn to releasethe film so that the feeding jaws can advance they film longitudinally.

As the carrier moves away again, the auxiliar jaws 87 again l0ck, andremain so, unti tie carrier has reached its opposite end position oftravel,L when the action is repeated. i

As the film isy fed down, it is tightly wound. up on theftalre-up spool107, the arm 113 controlling the pawl 112, being caused to oscillate bythe spring lever arm or compensating arm' 115, which spring arm nemesiwill absorb the strain transmitted to it should the film be tightlywound on. the spool 107 and thus protect the film against injury.v

After the film has passed'f through the camera, the camera can then beopened and the iilm taken. out and developed in the ,usual Way. Afteradjustment of the present camera for any shrinkage of the negative, thepositive can be printed in the camera, or the negativecan be removedlfrom the camera and the positive obtained in any well known manner, andthe positive how ever obtained from said negative, can be projected ,bythe present camera after adjustmeut of the before described means of.the camera forshrinhage of the positive.

,From the foregoing it willbe seen, that the orifice 127 registeringwith` the lens 20 will. direct the light passage when' taking/apicture,that the condensing lens 164 will direct the light passage whenreproducing positives from negatives, in which case'the orifice 127 ispreferably closed; and that the condensing lens 164, lens 20 and orifice127 will direct the light passage when proj jecting pictures. t
